This research paper reviews the causes, and the effective and safe therapy for anxiety disorders. Anxiety disorders affect one-eighth of the total population worldwide, and have become a very important area of research interest in psychopharmacology. People with anxiety disorders can benefit from psychological treatments, pharmacotherapy or a combination of the two. Common limitations of conventional antianxiety therapy include co-morbid psychiatric disorders and increase in dose of drugs leading to intolerable side effects. These limitations have prompted the use of traditional and alternative systems of medicine.
